So I started fixing up a Stumpjumper Comp from, I believe, 1988. It has all original parts (Deore XT) except for the front cantilevers (it has a rear U brake). The bike has barely been ridden but it has some issues that I need some help with.
(1) So I have no idea what is the tool I need to remove the 6 speed cassette. I'm attaching a pic.
(2) The locknut for the stem is frozen in the headtube. I shot it full of WD 40 and we'll see what happens. Any great ideas for how to get it out?
(3) The seatpost binderbolt for the saddle is frozen. I shot it full of WD 40; any great ideas for how to loosen it up?
Other than that, I overhauled the front hub and it is in prima shape. The bb looked almost brand new but it was ruined because some cretin overtightened it. It has biopace chain rings and the cool quasi-motorbike brake lever protectors that mountain bikes used to have (like I said, other than the front cantis and the saddle, this bike is, I believe, pretty much original). This bike has very few miles on it and will make a great bike once I get it fixed up:
